Consider a cellular system in which an average holding time of a call is $300$ second, and the probability of blocking is to be no more than $2\%.$ Assume that every subscriber makes $0\mathrm{.}2$ calls per hour on average. If there are a total of $490$ traffic channels for a $7-$cell reuse system. Find the number of users that each cell can support.R teizx XXXxxxxzxddzzz
